JOINT BI-LEVEL IMAGE GROUP
(ISO/CCITT/JBIG)
ADVANCE CALL FOR PROPOSALS
PROGRESSIVE BI-LEVEL IMAGE COMPRESSION/DECOMPRESSION ALGORITHMS
A CCITT working group involved with image communication
(CCITT Study Group VIII: Special Rapporteur Group on
Standard Components for Image Communication) and an ISO
working group on picture coding (ISO/IEC/JTC1/SC2 Working
Group 8: Coded Representation of Picture and Audio
Information) have formed a Joint Bi-Level Image Group for
the purpose of identifying, evaluating, refining, and/or
otherwise developing one or more image
compression/decompression algorithms for use with digital
representations of bi-level images (typically black and
white, but also including other types of two-colour images).
As a minimum, such algorithms must be progressive in nature
(i.e., must provide for a staged image build-up providing
successively higher levels of picture integrity); must be
information preserving at the final stage; and must be at
least as efficient in terms of compression at the final
stage as the current CCITT Group 4 MMR algorithm at its
final information preserving-stage.
Present plans call for a definitive requirements definition
document to be available in June, 1988.
Definitive proposals describing compression/decompression
algorithms considered to be responsive to these requirements
will then be solicited. For planning purposes, the
submission date is currently expected to be no later than
the end of August, 1988.
Persons interested in contributing one or more algorithms or
participating in the group should notify one of the
following individuals:
